FIGJH- UNITED STATES ATE rricno WILLIAM H. PAINE, OF BROOKLYN, NEXV YORK.

SPECIFICATION forming part of Letters Patent No. 331,238, dated November 24, 1885.

Application filed April 18, 1885.

To all whom/it may concern:

Be it known that 1, WILLIAM H. PAINE, a citizen of the United States, residing at Brooklyn, in the State of New York, have invented certain new and useful Improvements in Hand Mechanism for Operating Grippers for Cable Railways, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,in which- Figure I is a plan of my improved hand mechanism. Figs. II and III are elevations of the same, looking in the directions of the arrows 2 and 3, respectively, Fig. I.

This mechanism is designed particularly for operating a grip such as described in another application of mine filed on the 30th day of April, 1885, Serial No. 164,001, and which is opened and closed by the opening and closing of apair of levers pivoted to each other in such a manner as to operate as togglelevers, said levers being moved in opposite directions by an endless belt or chain passed around winding disks or drums at the respective ends of the car, and to the oppositely-moving parts of which said levers are respectively connected. This mechanism is not confined,however,to use in connection with an endless belt or chain and a pair of grip-levers connected thereto and moved thereby, but may be used to operate a grip having asingle arm or lever connected with the operating mechanism by means of a single rope, chain, or other connection.

In the drawings a section of this endless connection is shown at a, while b represents one of the winding disks or drums located beneath the platform, a fragment of which is shown at c.

d is the iron frame or railing to which the dash-board of the car is secured.

e is a casting, which will be hereinafter referred to as a rack-plate, secured to the railing d by bolts and nuts f. This rack-plate is substantially of the form shown in the plan view, Fig. I, and is apertured at g for the passage of the winding-staff h, the lower end of which works within suitable bearings in platform 0 of the car.

i is a disk secured rigidly to the windingstaff h and formed with a notch, j, in its periphery,for the purpose to be hereinafter fully set forth.

Serial No. 169,702. (No model k is the handlever, which is pivoted loosely on the upper end of the staff h, and is capable of being turned thereon in the direction of the arrow. This lever is here shown in its retracted or inoperative position, where it is held by the engagement of a dog or latch, Z, with a notch, 112, formed in the rack-plate c. This latch Z is pivoted to the hand-lever k at n, and provided with a handle, Z, within convenient reach of the handle of the lever 7c, so that both may be grasped by the one hand of the operator when the grip is to be applied or released. The nose of this latch is held normally out or in position to engage automatically by a spring, 0, interposed between its heel and a lug, k, projecting downward from the lever 70.

p is a dog pivoted to the hand-lever at p, and g a spring interposed between the heel of said dog and a lug, k", projecting downward from the lever 70, whereby the nose of said dog tends always to engage with the notch j in the disk t. When, however, the handlever is in the position shown in Fig. I, the heel of this dog is engaged by a lug or other tripping device,r,1: rojecting upward from the rack-plate e. WVhile in this position,the staff h may turn freely, which is necessary if the grip is to be operated from the other end of the car; but just so soon as the latch Z is released from its notch in and the lever is moved ashort distance in the direction of the arrow, the dog p,being no longer held out of engagement by the trip r, will have its nose forced by the spring (1 into the notch j of the disk 2'. Any. further movement of the lever is after this engagement of the dog has taken place will therefore rotate the staff it, and thereby cause the endless chain or other connection to move as required, and close the jaws of the grip. To look the grip, this movement of the handlever is should be continued until the latch Z falls into engagement with one of the notches s of the rack if,formed on the rack-plate 6. This mechanism for operating grips is rendered plishing this result are described and claimed in my application above referred to.

Having thus described my invention, the fol- IOO - engagement with the winding-staff when the hand-lever is out of operative position, substantially as set forth.

3. The combination, with the winding-staff having a notched disk secured thereto, of a hand-lever pivoted to said staff, an automatic dog pivoted to said lever and adapted to engage with said disk, and a trip for holding said dog out of engagement, in the manner and for the purpose set forth.

4. The combination, with the gripper, the winding-staff, and connection between them, of 2 5 a hand-lever pivoted to said staff, and a dog for connecting said hand-lever and staff at the will of the operator,substantially as set forth.

5. The combination, with the winding-staff h and the concentric notches m s, of the hand- 0 lever Zc,piv0ted to the staff h, and provided with latch l, substantially as and for the purposes set forth.

6. The combination, with the staff h, having the notched disk i, of the hand-lever k, 5 pivoted thereto, the dog 19, and the latch Z, pivoted to said lever 70, and provided with the springs q and 0, respectively, the trip 7', and the notch m, all constructed and arranged to operate substantially as and for the purposes 40 A set forth.
